we are currently working with Jitsi connected to a Cisco UCM 8.0.
Everything is working OK if i use G711u or G711a. If we enable ilbc we
get a interesting error:
Signalling wise everything seems to be going OK, we see both sides use
the (seemingly) correct SDP.
In the Jitsi Logs I actually see we are not sending any packets:
stats for outgoing audio stream SSRC:16493548
rtpstat:bytes sent: 0
rtpstat:RTP sent: 0
rtpstat:remote reported min interarrival jitter : -1
rtpstat:remote reported max interarrival jitter : 0
rtpstat:local collisions: 0
rtpstat:remote collisions: 0
rtpstat:RTCP sent: 4
rtpstat:transmit failed: 0
So it does not look like a codec mismatch problem I think.
this is also confirmed via the packet capture. I'm not sure why this
is happening only with ilbc, maybe someone can help me out
I have attached both the Packet captures for both calls as well as the
SIP Comm. version is 1.0-beta1-nightly.build.3364
